Last reviewed 01/2018

The Tanner assessment of pubertal development is used to give a standardised way of refering to pubertal staging. For each sex there are three scores; 0 is prepubertal and 5 is postpubertal. Scoring is based on:

  • breast development in girls, genital development in boys
  • pubic hair development
  • axillary hair development
